摘要： A recording and reproducing apparatus is characterized in that said apparatus has: inputting means for receiving a packet data which is based on IEEE 1394, and in which signal information for indicating copy right information of an AV data (hereinafter, referred to as EMI) is provided in a header of a packet according to IEEE 1394; and recording and reproducing means for recording and reproducing an AV data and the EMI which are held in the packet data received by said inputting means. Four kinds of EMI are used, and, when an AV data indicating allowance “copy one generation” among them is to be recorded, said recording and reproducing means performs recording while rewriting the EMI to EMI indicating “no more copy.”

摘要： The problem to be solved is that once copyright claimed AV data is passed to application software, the application software can freely process the AV data for recording, etc., defeating the purpose of copyright protection. The invention provides a computer which comprises a system section 12 and an application software section 13, and which takes in copyright claimed, encrypted data via a digital interface 1 for processing therein, wherein the system section 12 judges that the application software section 13 is legitimate application software for the protection of copyright, and if the application software is a legitimate one, the system section 12 passes a key for the encrypted data to the application software section 13.

摘要： A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STB 1 transmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR device 2 decrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB 1, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.

摘要： In the conventional file management system, there is a problem that even a file assigned permission information can be processed without considering any permission information. Therefore, the system includes a first accumulation device 2 for accumulating files to which permission information is added, and a new file management apparatus 7 for performing an input/output process on files with a request for a process from the application A 10 accessing the file management system taken into account according to the permission information added to the file. The new file management apparatus 7 compares the permission information added to the file in the first accumulation device 2 with the request contents of the process for the file from the application A 10, determines whether or not the process can be performed on the file, inputs the file from the first accumulation device 2 based on the result, and outputs it to the application A 10.

摘要： Methods to set a viewing and/or listening term are classified into two types, which are a fixed-time-length type to limit time length and a fixed-expiration-time type to limit expiration time. And the timings of license acquisition are classified into two types which are an immediate-acquisition type and a point-of-use type. The type of the timing of license acquisition is written to a meta data which is to be sent to a terminal before initiating download. The terminal determines the timing of license acquisition according to the meta data. When contents are point-of-use type, the terminal doesn't acquire a key and an expiration time information until a time of initiating playback. On the other hand, when contents are immediate-acquisition type, the terminal acquires the key and the expiration time information at any point of time. Since the key is acquired at the early timing such as download completion timing, a reaction velocity in response to a playback instruction can be heighten.
摘要翻译：设置观看和/或听力项目的方法被分为两种类型，它们是限制时间长度的固定时间长度类型和限定到期时间的固定期满时间类型。许可证获取的时间分为两种类型，即立即采集类型和使用点类型。许可证获取的时间类型被写入要在开始下载之前发送到终端的元数据。终端根据元数据确定许可证获取的时间。当内容是使用点类型时，终端在开始播放之前不获取密钥和到期时间信息。另一方面，当内容是即时获取类型时，终端在任何时刻获取密钥和到期时间信息。由于在诸如下载完成定时的早期定时获取密钥，所以可以提高响应于播放指令的反应速度。
